    摘要： Detection means for detecting information in a signal, comprising integration means for integrating the signal over time such that the integration means is periodically reset at about the start time reference of a periodic time interval; and a sample&hold circuit for periodically sampling and holding the integrated signal (int) at about an end time reference of the periodic time interval and thereby delivering a further signal (fs). The detection means further comprises a chain (CHDL) of signal time delay elements, an input of the chain (CHDL) being coupled to receive the further signal (fs); and combining means (CBMNS) having combining inputs coupled to signal taps of the chain (CHDL), such that the number of the combining inputs and the position of coupling the combining inputs to the signal taps of the chain (CHDL) correspond to the information in the signal.

    摘要： A method of selecting a generator matrix (G) for encoding information words (m) including information symbols (m1, m2, mk) into codewords (c) of a code (C) provides an enhanced error correction capability if at least one information symbol (m1, m2, m3) is known a priori to a decoder decoding received, possibly mutilated codewords (r). In order to design a code of which the correction power is enhanced if some information symbols are known to the decoder prior to decoding, the generator matrix (G) is selected such that the minimum Hamming distance of at least one subcode (C′) of the code (C) is larger than the minimum Hamming distance of the code (C), and that a subcode generator matrix (G′) of the at least one subcode (C′) is derived from the generator matrix (G) of the code (C) by omitting the at least one row from the generator matrix (G) corresponding to the at least one a priori known information symbol (m1, m2, m3).
